The prolactin hormone helps stimulate brain cell growth, specifically in areas linked to the sense of smell, which enhances emotional bonds between individuals.
The Effect of Prolactin on Brain Cell Growth
The pituitary gland in mammals secretes prolactin. Levels of this hormone rise in specific situations, such as during pregnancy and postpartum to stimulate milk production in mothers; it also increases in both men and women following orgasm.
Research conducted on mice revealed that this hormone leads to:
- An increase in the number of new cells in the olfactory region of the female brain during and after pregnancy.
- Stimulation of similar cell growth when male and female mice are injected with prolactin serum.
- Development of the sense of smell in mice, enhancing their ability to recognize and raise their offspring.
Emotional Bonds and Olfactory Memory
One hypothesis suggests that the effects of prolactin may extend to humans. Increased levels after orgasm may lead to the storage of specific scents in the memory, helping to build a long-term relationship between partners. However, linking the increase of cells in the olfactory region to maternal behaviors in humans remains difficult due to the complexity of these behaviors compared to those of mice.
Future Medical Perspectives
Researchers are studying the medical implications of this hormone, investigating its potential to stimulate stem cells to produce replacement cells in areas damaged by a stroke.
FAQ
What stimulates brain cell growth?
This occurs through the secretion of prolactin by the pituitary gland, which in turn stimulates the production of new cells in the brain region responsible for the sense of smell.
When does brain cell growth stop?
Available sources do not specify a particular time when this process stops, but rather focus on periods of increased activity, such as pregnancy and the postpartum period.
What is the relationship between prolactin and emotional bonds?
It is believed that stimulating the growth of cells in the olfactory region helps form an olfactory memory that contributes to strengthening the relationship between a mother and her children, as well as between partners.
When to Visit a Doctor?
It is recommended to consult a healthcare provider if you notice concerning neurological signs, such as:
- Sudden memory loss.
- Appearance of stroke-like symptoms.
- Severe disturbances in cognitive or sensory functions.
